APPARATUS FOR CHEMICALLY PRODUCING HEAT SPECIFICATION forming part of Letters Patent No. 387,089, dated July 31, 1888.

(No model.)

To aZZ whom it may concern.-

Be it known that I, W ILLIAM G. MA OIJAUG'I'I' LIN, a citizen of the United States of America, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Apparatus for Chemically Producing Heat; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer ence being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specifica- [5 tion.

My invention relates to new and useful improvements in an apparatus for chemically producing heat for cooking purposes, heating cars, and using the vacuum caused by condensation after heating to run machinery, the

same consisting of a novel construction and arrangement of parts, which will be more fully hereinafter described, and pointed out in the claims.

The object of my invention is to provide an apparatus for aiding and controlling the pro d notion of heat through the medium of a chemical compound contained therein, and for regulating the feeding of the constituent parts of said compound relatively to each other. To

this end I employ a preferred form of apparatus, as illustrated in the accompanying drawin gs, wherein like letters of reference indicate similar parts in the several views, and in which Figure 1 is a transverse vertical section of the apparatus. Fig. 2 is a top plan view. Fig. 3 is an elevation of the same partially broken away. Fig. 4 is a top plan view of the valve- 0 head. Fig. .3 is a transverse vertical section thereof.

A indicates a metallic hopper having a head, J, bolted thereto and forming a tight connection therewith. This head is provided with a 4. 5 feed aperture having a removable screwplug, 1.

B indicates a cylinder having a head, D, fitted in the upper part thereof by means of screw-threads, and to this head D the lower 0 flanges of the hopper A are securely fastened. water.

The lower part of the cylinder B is also pro vided with a base rest or bottom, B, which is in removable connection therewith by means of screw-threads.

A tank, 0, is provided and secured to the upper part of one side of the cylinder B by means of a feed-pipe, G. In a screw-threaded connection or opening on the opposite side of the cylinder B an exhaust-pipe, G, is secured, and is adapted to convey the heat or steam formed by the apparatus to any point at a distance from the machine, as may be desired. The lower side of the cylinder B is also provided with a drain or cleansing pipe or cock, H.

The plate D is formed with an enlarged central opening and with aseries of small openings, d, running downward at an inward iiicline and connecting with the said enlarged central opening. A plug or circular valve, E, is fitted within the enlarged opening in the plate D, being carried at the lower end of the rod E, which passes up through the plate J of the hopper A, having a central bushing surrounding the same at the point where it en- 7 gages with the said plate J, and a lever, F, secured to the top thereof. The outer end of the said lever has movement in a space confined between two limiting-lugs, j, mounted on the top plate, J, near the periphery thereof. The valveplug E is also formed with a series of openings or apertures, c, which extend from the bottom thereof upward at an incline, and are adapted to register with the openings d in the plate D when the said valve-plug E is turned in proper position, and thereby estab lish communication between the cylinder B and the hopper A. Whenever the valve-plug E is turned or revolved through the rod E actuated by the lever F, the apertures 0 and d 0 will not register with each other, and access from the hopper A to the cylinder B will be shut off. The lever F will be arranged in such a manner that when it is turned a certain distance the apertures c and d will register, as 5 shown in Fig. 4.

Caustic soda moistened with water is placed within the tank or receptacle 0 in about the proportion of one pound of soda to one pint of Sulphuric acid is then placed in the too hopper A. The valve 0 in the connection between the tank or receptacle C, is opened, and aquantit'y of the soda and water is allowed to pass into the cylinder B, the volume of the said mixture being governed by the size of said cylinder. After depositing the soda and water into the cylinder B the lever F is turned until the apertures e and d will register with each other, and the sulphuric acid in the hop per A gradually fed upon the soda and water.

The proportion of the acid used in my improved method will be proportionate to the amount of soda used.

The heated air or steam generated by the mixture of the compound of soda and acid will pass out through the exit-pipe G, it being understood that all other valves and exits will have been closed. The heated air or steam thus passing through the pipe G may be used for various purposes, and is especially adapted for heating cars.

The advantage gained by this manner of generating heat is the absence of fire and smoke, and dispensing with the use of fuel.

It will be understood that the apparatus will be replenished from time to time with the chemicals hereinbefore stated and in such proportions as will be found mostdesirable.

I do not confine myself to the uses to which my invention could beapplied, nor to the exact construction of the apparatus herein set forth.

The method employed in the apparatus above described is fully set forth and claimed in a pending application filed by me December 30, 1887, Serial No. 259,411; and Ido not therefore herein claim the same.

Having thus described my invention, I claim' 1. In the apparatus set forth, the combination, substantially as hereinbefore described, of the cylinder B, the hopper A, having a head, J, mounted on and geared to said cylinder, the removable head D, having an enlarged centrally-situated aperture, and small apertures d adjacent thereto, the rod E, the lever F, the apertu-red valve-plug E on the lower end of the rod E, having apertures e therein adapted to register with the apertures d in the head D, the tank 0, connected to the cylinder B and having asuitable cut-off plug, C'Zand its connecting-pipe, the exhaust-pipe G, and the drain-pipe H.

2. The combination, with the hopper 'A, having a closed head, the cylinder 13, having a removable head-plate, D, with central apertures, the rod E, lever F, the valve-plug E, carried on the lower end of the rod E, having apertures e therein adapted to register with the apertures in the plate D adjacent thereto, a soda and water supply tank, and an exhaustpipe, substantially as described.

3. The combination,with the hopper A, the cylinder B, head-plate D, having a central aperture with smaller apertures running thereinto at an incline, the lever B, the rod E, and the valve-plug E, carried on thelowerend of the rod E, having apertures e therein re istering with the apertures (Z in the plate D, substantially as described.

4. The combinatiomwith the cylinder B and hopper A, of the apcrtured plate D between the same, the head J on top of the hopper A, having lugsj thereon, the lever F, moving between said lugs j, the rod E,and the apertu red valve-plug E on the lower end of the rod E, and fitted in the enlarged central aperture in the plate D,having apertures etherein adapted to register with the apertures d in the said plate D, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
